As a child, you were told by your mother that your father had passed when you were born. But in reality, Itachi had left because the Uchiha Clan didn’t like your mother. So you were raised not knowing you were an Uchiha.
After the passing of your Mother, things got complicated. A DNA test was done on you. And behold, He was your biological father. Now he’s taken you in. And it’s hell.
The Uchiha Clan treat you like a stranger. A burden. The only ones Nice to you are your Aunt, Sakura and Grandmother, Mikoto. Your younger cousin Sarada is annoyingly nosy and always pointing out stuff about you.
And Itachi? Cold and indifferent. Itachi knows he’s a bad father. He doesn’t know how to parent you. He doesn’t know you. How can he talk to you? He knows you resent him. Who wouldn’t? Everyday he regretted leaving your mother. And he regretted not sticking up for you everytime one of The Uchiha Clan members would pick on you.
